Description

A ball valve ball cutting device and method Technical Field

[0001] This invention relates to the field of machining technology, specifically to a ball valve ball cutting device and method. Background Technology

[0002] Ball valves, as fluid control devices, are widely used in various industrial pipeline systems. The valve ball, as the core component of a ball valve, directly affects the overall performance of the valve due to its quality, precision, and performance. Therefore, the manufacturing process of the valve ball requires high-precision, high-efficiency cutting equipment to ensure its quality. With the continuous development of industrial technology, ball valve cutting equipment is also constantly being upgraded and improved. Traditional cutting equipment may employ simple machining methods, resulting in limited machining accuracy and efficiency. Modern cutting equipment, on the other hand, may incorporate advanced technologies such as CNC technology, high-precision measurement technology, and automated control, significantly improving machining accuracy and efficiency.

[0003] To improve production efficiency, ball valve cutting equipment typically employs high-speed spindles, large feed rates, and large depths of cut, among other high-efficiency cutting technologies. These technologies significantly increase cutting speed and material removal rate, shortening production cycles. Cutting tools and fixtures are crucial components of cutting equipment, significantly impacting machining quality and efficiency. Modern ball valve cutting equipment generally utilizes advanced tool materials and coating technologies to enhance tool durability and cutting performance. Simultaneously, precision fixture technology ensures the stability and accuracy of the valve ball during the cutting process.

[0004] Existing ball valve ball cutting equipment results in a rough surface on the ball valve ball during the cutting process. This roughness increases friction between the ball and the valve seat, leading to a shorter service life and potential leakage due to poor sealing. Therefore, it does not meet current requirements. To address this, we propose a ball valve ball cutting equipment and method. Summary of the Invention

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example

[0040] This embodiment aims to address the problem that during the cutting process of a ball valve ball, the surface of the ball becomes rough due to the cutting of the tool. This roughness increases friction between the ball and the valve seat, leading to a shortened service life of the ball valve and potentially causing leaks that affect later use due to poor sealing. Referring to Figures 1-13, a ball valve ball cutting device and method include a processing table 1 with a circular hole 11 in the center. Support legs 12 are fixedly connected below the processing table 1 to support the overall weight of the device, ensuring stability and reliability during processing. A disc 2 is rotatably connected within the circular hole 11, and a cutting tool 21 for cutting the ball 6 to be processed is mounted on the disc 2. The cutting tool 21 is based on existing technology and will not be elaborated further. To elaborate further, the combined design of the disc 2 and the cutting tool 21 enables the cutting tool 21 to perform arc-shaped cutting of the valve ball 6 under the operation of the disc 2. A power assembly 3 is provided below the disc 2 to provide power to the disc 2. A power motor 13 is installed on one side of the circular hole 11 to drive the valve ball 6 under the operation to rotate. The design of the power motor 13 enables the valve ball 6 under the operation to rotate, thereby completing the cutting of the valve ball 6 under the operation of the cutting tool 21. The power motor 13 is installed on the machining table 1, and a transmission assembly 4 for transmitting power is installed on the machining table 1. The transmission assembly 4 is connected to a grinding assembly 5 for grinding the valve ball 6 under the operation. This integrated design enables the surface treatment of the valve ball 6 under the operation after cutting, thereby improving product quality.

[0041] In this embodiment, a first bevel gear 22 is fixedly connected above the disk 2, so that the first bevel gear 22 can rotate while the disk 2 rotates during the cutting process. The first bevel gear 22 is located in the middle of the disk 2. This design helps to ensure the stability and balance of the transmission system. A receiving plate 23 for receiving the cut-off chips is fixedly connected in the middle of the first bevel gear 22. This helps to maintain the cleanliness of the processing area, prevent the interference and mixing of chips, and improve the efficiency of the cutting operation.

[0042] In this embodiment, the transmission assembly 4 includes a first double-ended bevel gear rod 41 meshing with the first bevel gear 22, and a second double-ended bevel gear rod 42 meshing with the other end of the first double-ended bevel gear rod 41. This structural design enables the two gears in the transmission system to work together, ensuring effective power transmission. Both the first double-ended bevel gear rod 41 and the second double-ended bevel gear rod 42 are designed with bevel gears at both ends of the rod. Both the first double-ended bevel gear rod 41 and the second double-ended bevel gear rod 42 are rotatably connected to a protective shell 43. The protective shell 43 is used to prevent falling debris from affecting the transmission, effectively preventing debris generated during the cutting process from entering the transmission assembly 4, reducing the interference and damage of debris to the transmission components, and improving the reliability and lifespan of the transmission system. A fixing block 44 for limiting the position is fixedly connected to one side of the protective shell 43. One end of the fixing block 44 is fixedly installed on the processing table 1, which helps to ensure that the transmission assembly 4 remains stable during operation, reduces system vibration and friction, and improves the reliability of the entire system.

[0043] In this embodiment: one end of the second double-ended bevel gear rod 42 is meshed with a second bevel gear 45, the second bevel gear 45 is rotatably connected to an arc-shaped block 46, and one end of the second bevel gear 45 passes through the arc-shaped block 46 and is connected to a traction belt 47. This design ensures transmission while realizing the traction effect of the traction belt 47, which is important for subsequent motion control and transmission to other components. The traction belt 47 is located inside the arc-shaped block 46, and a sliding groove 48 is provided inside the arc-shaped block 46. A sliding track 49 is provided below the sliding groove 48. The traction belt 47 is arranged in an arc shape, and the sliding track 49 is provided on the arc-shaped block 46. One end of the slide 49 is provided with an ascending track 410. The design of the ascending track 410 allows an object sliding in the sliding track 49 to slide upwards, changing the trajectory of the object. Both the sliding groove 48 and the sliding track 49 have the same arc design as the arc block 46. The other end of the ascending track 410 is downward and connected to one end of the sliding track 49. A movable guide block 411 is provided at the junction of the ascending part of the ascending track 410 and the sliding track 49. The movable guide block 411 can guide the object sliding in the sliding track 49 into the ascending track 410. The movable guide block 411 is hinged to the arc block 46.

[0044] In this embodiment: an arc-shaped rack 412 is provided below the sliding track 49, and an arc-shaped abutment block 413 is provided on one side of the arc-shaped rack 412. The arc-shaped rack 412 and the arc-shaped abutment block 413 are both fixedly installed on the arc-shaped block 46. Both ends of the arc-shaped block 46 are fixedly connected to fixing posts 414 for fixing the arc-shaped block 46. The ends of the fixing posts 414 are fixedly installed on the processing table 1. This helps to maintain the stability of the entire structure, prevent unnecessary shaking and vibration during operation, and also ensure the accurate positioning of the arc-shaped block 46.

[0045] In this embodiment: the grinding component 5 includes a sliding ball 51 fixedly connected to the traction belt 47. The sliding ball 51 is slidably connected to the sliding groove 48. The traction belt 47 drives the sliding ball 51 to slide in the sliding groove 48. A round tube 52 is fixedly connected to the sliding ball 51. A groove 53 is opened on the round tube 52. A telescopic rod 54 is slidably connected inside the round tube 52. A control rod 55 is fixedly connected to one end of the telescopic rod 54. One end of the control rod 55 is slidably connected to the groove 53. The other end of the control rod 55 is slidably connected to the sliding rail 49 and the rising rail 410. This connection allows the control rod 55 to drive the telescopic rod 54 to extend and retract inside the round tube 52 during the sliding process. A mounting block 56 is fixedly connected to the other end of the telescopic rod 54.

[0046] In this embodiment: a transmission gear 57 is rotatably connected to the mounting block 56. The transmission gear 57 meshes with the arc-shaped rack 412. When the telescopic rod 54 slides within the rising track 410, it drives the telescopic rod 54 to slide into the circular tube 52. When the telescopic rod 54 drives the mounting block 56 to slide upward, it causes the transmission gear 57 to mesh with the arc-shaped rack 412, thereby driving the transmission gear 57 to rotate. One end of the transmission gear 57 is connected to a transmission belt 58, which passes through the mounting block 56. A rotating column 59 is rotatably connected to the mounting block 56. There is significant friction between the rotating columns 59 to prevent them from rotating too much. A grinding block 518 is fixedly connected to one end of each rotating column 59. The rotating column 59 is connected to the transmission belt 58. A transmission groove 510 is provided on the other side of the grinding block 518. The transmission groove 510 has a two-section design, one section being square and the other circular. A connecting column 511 is rotatably connected within the transmission groove 510. The connecting column 511 also has a two-section design, one section being circular and the other square. The square design is used to prevent the grinding block 518 from rotating during the grinding process. A control angled rod 512 is fixedly connected to the column 511. The control angled rod 512 is used to abut against the arc-shaped contact block 413. A spring 513 is fixedly connected to one end of the connecting column 511. The spring 513 is fixedly installed in the mounting block 56. A spring 514 is fixedly connected to one side of the grinding block 518. The presence of the spring 514 helps to maintain the elasticity of the grinding block 518 during the grinding process and improves the stability of the grinding. A low-grit grinding disc 515 is fixedly connected to one end of the spring 514. A guide rod 51 is provided on one side of the spring 514 to maintain stability. 6. The design of the guide rod 516 prevents the grinding disc from tilting unnecessarily during the grinding process, thus affecting the grinding effect. The guide rod 516 is fixedly installed between the grinding block 518 and the low-grit grinding disc 515. The other side of the grinding block 518 is connected to the high-grit grinding disc 517. The connection method between the high-grit grinding disc 517 and the grinding block 518 is the same as the connection method between the low-grit grinding disc 515 and the grinding block 518. Through the combination design of the low-grit grinding disc 515 and the high-grit grinding disc 517, the valve ball 6 to be processed can be ground more smoothly.

[0047] In this embodiment: the power assembly 3 includes a servo motor 31 fixedly connected to one side of the disk 2, which can provide efficient and precise power to drive the rotation of the disk 2. A support platform 32 is provided below the servo motor 31 to support the servo motor 31, which helps to maintain the stable position of the servo motor 31, reduce vibration and sway, and improve the stability of the entire system. A fixing rod 33 is fixedly connected to the support platform 32, and one end of the fixing rod 33 is fixedly connected to the processing table 1, which helps to ensure the fixation of the servo motor and the robustness of the entire system.

[0048] This embodiment includes the following steps:

[0049] S1: First, the valve ball 6 to be processed is fixedly installed on the power output end of the power motor 13. This ensures that the valve ball remains stable throughout the processing, which is beneficial for subsequent cutting and grinding operations.

[0050] S2: Then turn on the power motor 13 to drive the valve ball 6 to be processed to rotate. This step guides the start of the entire processing process, so that the valve ball 6 to be processed starts to rotate, preparing for subsequent cutting and grinding operations.

[0051] S3: Simultaneously turn on the servo motor 31 to drive the disc 2 and the tool 21 to cut around the valve ball 6 to be processed. This step utilizes the precise control of the servo motor 31 to achieve the cutting of the surface of the valve ball 6 to be processed, ensuring the accuracy and quality of the cutting.

[0052] S4: While the disc 2 rotates, the grinding component 5 is driven by the transmission component 4 to grind the valve ball 6 to be processed. The design of the transmission component 4 ensures the movement of the grinding component 5, thereby realizing the grinding of the surface of the valve ball 6 to be processed.

[0053] S5: When the grinding component 5 slides to the other end of the sliding groove 48, the grinding block 518 is flipped by the cooperation of each component. When the grinding component 5 returns, the surface of the valve ball 6 to be processed is ground again by the high-grit grinding disc 517. This step realizes the flipping of the grinding block 518 and the re-grinding by the high-grit grinding disc 517. Through repeated grinding, the smoothness and precision of the final processed surface are ensured.

[0054] Working principle: First, fix the valve ball 6 to be processed on the power output end of the power motor 13. After installation, start the power motor 13 to rotate the valve ball 6 to be processed. Then start the servo motor 31 to drive the disc 2 to rotate. While the disc 2 is rotating, it drives the tool 21 to rotate around the valve ball 6 to be processed. While the tool 21 is rotating, it cuts the surface of the valve ball 6 to be processed.

[0055] As the disc 2 rotates, it drives the first bevel gear 22 to rotate as well. The first bevel gear 22 rotates, which in turn drives the first double-ended bevel gear rod 41 to rotate. The first double-ended bevel gear rod 41 rotates, which in turn drives the second double-ended bevel gear rod 42 to rotate. The rotation of the second double-ended bevel gear rod 42 drives the second bevel gear 45 to rotate, which in turn drives the traction belt 47 in the arc-shaped block 46 to rotate. The rotation of the traction belt 47 drives the sliding ball 51 fixed to it to slide in the sliding groove 48. The sliding ball 51 drives the round tube 52, the telescopic rod 54 and the mounting block 56 to move together, and at the same time, the control rod 55 slides in the sliding track 49. This causes the mounting block 56 to drive the grinding block 518 to grind the cut areas on the valve ball 6 to be processed. When the tool 21 moves from one end of the valve ball 6 to the other end, the reverse rotation of the servo motor 31 drives the disc 2 to rotate in the opposite direction, causing the tool 21 to move back, thus causing each component to move in the opposite direction.

[0056] When the control lever 55 moves to the rising track 410 within the sliding track 49, the movable guide block 411 causes the control lever 55 to slide into the rising track 410, thereby causing the telescopic rod 54 to extend and retract into the circular tube 52. As the telescopic rod 54 retracts inward, it drives the mounting block 56 to slide upward, causing the transmission gear 57 to mesh with the arc-shaped rack 412. Simultaneously, the control lever 512 abuts against the arc-shaped contact block 413, and the connecting column 511 slides within the transmission groove 510, causing the square section of the connecting column 511 to slide out of the square section of the transmission groove 510. This causes the grinding block 518 to lose its fixation by the connecting column 511, at which point the spring 513 deforms, causing the grinding block 518 to... When the component loses its fixed position, the transmission belt 58 rotates under the rotation of the transmission gear 57, causing the transmission belt 58 to rotate the rotating column 59. At the same time, the grinding block 518 flips over, and the length of the arc-shaped rack 412 is just enough to rotate the grinding block 518 180°, causing the low-grit grinding disc 515 to flip up and the high-grit grinding disc 517 to flip down. This allows the high-grit grinding disc 517 to grind the surface of the valve ball 6 to be processed when the component moves. At the same time, the control rod 512 is no longer resisted by the arc-shaped abutment block 413. Under the action of the spring 513, the square segment of the connecting column 511 continues to be inserted into the transmission groove 510, thus fixing the grinding block 518.

[0057] After the grinding block 518 completes its flipping, the control lever 55 continues to slide from the rising track 410 into the sliding track 49. When it slides back to the movable guide block 411, the control lever 55 pushes open the movable guide block 411, allowing it to continue sliding within the sliding track 49. The movable guide block 411 is a flexible steel sheet and moves in one direction. A similar movable guide block 411 is also provided at the descent point where the rising track 410 connects to the sliding track 49, used to guide the control lever 55 back into the sliding track 49. When the control lever 55 slides to the movable guide block 411 at the rising position, the movable guide block 411, after being pushed open, returns to its initial position under the action of elasticity, ensuring that one end of the movable guide block 411 always adheres to the sliding track 49, preventing the control lever 55 from being moved during sliding. The movable guide block 411 is engaged, and under the guidance of the movable guide block 411, the control rod 55 can slide into the rising track 410, thereby enabling the telescopic rod 54 to drive the mounting block 56 to slide upward. When the control rod 55 slides back to the sliding track 49, it slides to the movable guide block 411 and pushes one end of the movable guide block 411 open, causing the movable guide block 411 to deform. After the control rod 55 slides away from the movable guide block 411, under the action of elasticity, one end of the movable guide block 411 continues to stick to the sliding track 49. This design ensures that when the control rod 55 drives the mounting block 56 back to slide downward, the transmission gear 57 does not mesh with the arc-shaped rack 412, and at the same time, the control angle rod 512 does not collide with the arc-shaped contact block 413, preventing the grinding block 518 from flipping when sliding back.

[0058] When the grinding block 518 moves to the rising track 410, the surface of the valve ball 6 to be processed after being cut has been ground. Through this reciprocating motion, the surface of the valve ball 6 to be processed gradually becomes smooth.
